| Uses | Main Uses: Dimethylformamide (DMF) is an important chemical raw material and a solvent with excellent performance. It is also an important intermediate in organic synthesis. It can be used to produce dimethamidine in the pesticide industry; it can be used to synthesize iodosamine in the pharmaceutical industry. , Doxycycline, Cortisone, Vitamin B6, etc. Dimethylformamide also has a catalytic effect, which reduces the reaction temperature and improves the purity of the product. Although it is a "universal solvent". | ||
